Flock Master 64 - That reminds me of the doorbell I soldered in science class.
I wanted to use it in my house...but I forgot about it when we were building it until it was too late.
myback40 - To be honest, I'm not sure how high a rat can jump. The only thing I know is that they can't climb smooth plastic or metal. And that as fast as a mouse is...a rat is that much faster. Ugh!
I've seen You Tube videos on using a tube and a barrel or garbage can where the rats fall into it. But I'm sorry, I don't know the specific height on those.
We've had mice that fall into a five gallon pail and not be able to get out. I would "think" a 77 liter garbage can or bigger would be comparable so they couldn't get out. But that's strictly a guess. I've seen something for mice on You tube...it was a pail with mesh for sides and a small hole in the lid...and the mice just kept falling in.
I greatly dislike having to dispatch the animals I catch. For as harsh or generic as I may have made it sound...I usually cry every time I need to deal with the animals I catch. If not always for the rats, definitely for the raccoons and little foxes. It's definitely not something I look forward to.
Thank you for the info on the Victor Electronic multi-kill. I'm going to have to look into that!
We haven't used poison, I'm afraid the chickens will get into it. (they get into everything...lol)
